DM-U106 5v/6v/7.4v 6A output UBEC 2s-6S/8-25.5V Input Switch Mode



UBEC is a external voltage stabilizing device, it works in switch supply mode and it used for high current or high voltage hobby equipment, it could supply power to the receiver, gyro, HV servo,high torque servo, platforms, image transmission, FPV and so on.


  1. 1   Output:6V/6A or 7.4V/6A (Changeable with an jumper);

  2. 2   Input:8-25.5V (2 to 6 cells Lipo battery pack, 6 to 16 cells NIMH battery pack);

  3. 3   Continuous output current 6A;

  4. 4   Burst output current 8A (≤15 Sec);

  5. 5   Ripple:<45mVp-p(@2A/12V);

  6. 6  Size:39mm*21mm*6mm (L*W*H);

  7. 7  Weight:14g(Including the cable and the ferrite rin


  1. 1   Designed with an advanced switch mode DC-DC regulator IC, the max efficiency of the chip is up to 90%;

  2. 2   The output current is very large, the continuous output current is up to 6A, and the burst output current is 8A;

  3. 3  A shield covers almost all the electronic components on PCB, and a special made filter(ferrite ring) is attached with the output wires to significantly reduce the electromagnetic interference;

  4. 4  With ultra-wide input voltage from 8V—25.5V

  5. 5  Shows the working status with an indicator(LED), lights when the output is in normal range.Or you need check the connection.


Although we have tried our best to reduce the electromagnetic interference caused by switch model UBEC, it may still cause some interference to the receiver. So please install the filter (ferrite ring) far away from the UBEC’s main board, and DON’T stack the filter on the main board. Please put the whole UBEC as far as possible away from the receiver.

How to use the UBEC:

If ESC HAS NOT built-in BEC function

No change is needed for the ESC, just connect the input cables of UBEC with the battery, and plug the output cable (connector) of the UBEC into one spare channel of the receiver.


If ESC HAS built-in BEC function

You must disable the built-in BEC function of the ESC, i.e. you need to cut the red wire in the trio of receiver wires. Simply use a pair of wire cutters to remove a short section of the red wire near the receiver connector, and insulate the cut wire with a bit of electrical tape.


Suggestion:You can use a sharp screwdriver to take the pin (with red wire) out from the BEC

connector of the ESC, and then insulate it with a bit of electrical tape for further use, so you needn’t cut the red wire by this method.
